I have a stage to which a complex animation is added, including one step in the process: addChild(bitmapxyz).

At the end of this animation, I need to give the viewer the option of closing it, removing the added items, in order to start and view other animations.

Tried without success:

stage.removeChild(bitmapxyz);

Get an 1120 error.

Not sure how to clean up the stage for this animation? Or maybe there's a way to create a child of the primary stage to hold the animation, then remove this stage.child? If this could work, can someone point me to how to add a child to a stage that then can hold what currently is being added to the stage?
